Fender: common faults and their symptoms

1. Corrosion
   • Changes in the structure of the lacquer coating are visible, most often close to the end of the component.
   • Sometimes there may be perforation damages, then holes are visible in the fender.
2. Mechanical damages
   • Cracks, spalls and small dents are visible on the component, which do not violate integrity of the lacquer coating.
   • If the defects are significant, damaged metal will be seen at the place of deformation.

How to repair or replace a fender?

Repairing a fender is pretty common procedure. It is performed when damages to the component are not critical. Usually, repair involves the following:

1. The damaged component is dismantled from the vehicle.
2. Theoriginal shape of the fender is restored with the use of special instruments.
3. The surface is treated with a degreasing agent, and minor irregularities are removed.
4. The surface is anti-corrosion treated, after which it is primed for obtaining perfect smoothness.
5. The components is painted, covered with lacquer, and polished.

This should be done only at a service station, since it is impossible to restore the initial shape of the component, and prevent further corrosion for yourself.

If damage is very extensive, or the design of the component does not involve its dismantling with subsequent installation, the fender is to be replaced. Replacement should preferably be made at a service station, since the level of work is significant; moreover, it often requires welding, which requires special knowledge and skills. Besides, errors during fender installation do not only entail deterioration of the vehicle appearance, but also reduce the service life of the component, making it vulnerable to corrosion.
